Blanco Fracture Zone: 2000 – 2015 Seismicity Animation

Posted on: June 1, 2015 Last updated on: June 1, 2015 Written by: Jay Patton Comments: 9
I put together an animation that includes the seismicity from 1/1/2000 until 6/1/2015 for the region near the Blanco fracture zone, with earthquake magnitudes greater than or equal to M = 5.0. The map here shows all these epicenters, with…

Blanco Fracture Zone Earthquakes!

Posted on: June 1, 2015 Last updated on: June 1, 2015 Written by: Jay Patton Comments: 12
This morning we had three earthquakes related to the Blanco fracture zone, a transform (shear) plate boundary. These earthquakes occurred quite a bit north of the bathymetric expression of the BFZ (though the M 5.8 is actually plotting closer to…

Earthquake along the Alaska Penninsula!

Posted on: May 29, 2015 Last updated on: May 29, 2015 Written by: Jay Patton Comments: 5
We just had an earthquake along the Alaska Peninsula. The magnitude is currently set at 6.7 on the USGS website. The Peninsula is a volcanic arc that forms as a result of the subduction of the Pacific plate beneath the…

Gorda plate earthquake: 2010 zone strikes again

Posted on: May 26, 2015 Last updated on: May 26, 2015 Written by: Jay Patton Comments: 7
Early this morning we had a small rumbler offshore of northern California, generally in the same location as the 2010.01.10 earthquake. I remember the 2010 earthquake very well as the ground shaking lasted over 20 seconds in Manila. Here is…
